I found this info on LS1TECH. We can make any adjustments need to make more truck oriented, then make a stick out of it


Intake

Free mods - 0-5rwhp

Lid - 5-10rwhp

Big article on lids and dyno comparisions here

Filter - 0-5rwhp

MAF -
Very controversial as to any real gains, may even show negative numbers due to the fact it will be tricking the computer to run lean due to the larger diameter of the housing (good for stock, since you will gain a few hp by running a little leaner than the factory slightly rich setting; however, bad for modified vehicles). Stock MAF's are good to 500+hp. Once you are beyond that I suggest you contact your tuner (or local speed shop if you are doing your own) to find out what they recomend. Some will suggest taking the maf out and doing a speed density tune, which relies solely on the front O2 sensors.

Holley Intake Manifold - 15-20rwhp

FAST 78mm Intake Manifold - 15-20rwhp

FAST 90mm Intake Manifold - 20-25rwhp

Sheet Metal Intake Manifold - 25+rwhp
Mainly for all out race engines or bigger CI engines.

Testing of Intake Manifolds Here
Also note that these hp figures can vary greatly due to cam size and head flow.

Ported Stock Throttle Body 5-10rwhp

Cold Air Induction (CAI) - 5-10rwhp

Nitrous - Typically the size of the jetting will be the horsepower increase. Some company's rate it in flywheel and some to the rear wheels.


Exhaust

Listen

Cat-back - 10-15rwhp

Duals - 15-20rwhp

Catted y-pipe 5-10rwhp

ORY y-pipe 5-10rwhp

Shorty Headers 5-10rwhp

Mid-Length Headers 10-15rwhp

Long Tube Headers 15-20rwhp

Misc.

Underdrive Pulley 5-10rwhp

Tune 10-20rwhp

Electric Water Pump 5-15rwhp

Please DO NOT take the maximum number for everything and add it together and think you will gain this by adding these mods.
